ROAD-MAKING MACHINE.

Application filed-February 28, 1928. Serial No. 257,657.

Our invention relates to road making machines and refers particularl to machines adapted for the laying of asp alt and similar plastic road making materials.

In the laying of asphalt and similar plastic materials it is essential that layers of uniform thickness be produced and it is further essential that means be employed whereby the thickness of such layers may be controlled.

The present usually employed method is to dump a lapge quantity of asphalt in one place and then carry it todifi'erent portions of the road bed and by means of hand rakes form it into a smooth surface.

This method is uneconomical, unscientific and uncertain in results.

The repeated handling of the heated asphalt frequently cools it to a consistency which is difficult or impossible to work. It requires a large number of workmen to carry the asphalt to the desired portions of road bed. It requires a large number of men to The formation of a uniform thickness is dependent upon the opinion of the workmen. The production of the desired thickness is obtained only by repeated and constant tests of depth. Any inequality of thickness requires an additional amount of working and raking of the rapidly cooling asphalt.

All of the above and many other objectionable features of the present employed methods are avoided and overcome by the device of our invention.

By the movement of our device there is continuously deposited upon a road bed, an asphalt layer of any desired thickness which is automatically smoothed and leveled, the amount of asphalt deposited being controlled by our device and its uniformity of thickness being accurately governed and insured by the scraping, or raking, device which is an element of our device.

As the asphalt is deposited from the conveying truck directly u on the road bed in the form of the desire layer, no carrying or shovelling is necessary.

1ft is evident, therefore, that by means of our device it is possible to accuratelydeposit a predetermined thickness of asphalt economicall efficiently and rapidly.

The a vantages of our device will be evident upon a consideration of our specification and its accompanying drawings.

Tn the accompanying drawings illustrating one form of the device of our invention similar parts are designated by similar numerals.

Figure 1 represents a broken top view of one form of the device of our invention.

Figure 2 is a side view of the device of Figure 1 partly broken away for purposes of clearness of description.

Figure 3 is an end view of the device of Figure 1.

Figure 4 is a broken top view of the scrapmg elements of our device.

Figure 5 is a section through the line 55 of Figure 2.

Figure 6 is a top view of the guiding elements of our device.

Figure 7 is an enlarged vertical section of the pocket changin elements of our device.

The particular orm of the device of our invention illustrated in the accompanying drawings comprises an asphalt receptacle having the sides 10 and 11, the front 12, the back 13 and the downwardly inclined bottom 14, the latter having a longitudinal opening 15 at the lower portion thereof. A hood 16 extends around the upper portion of the rear of the receptacle. The receptacle is mounted upon the two traction wheels 17, 17.

The revoluble shaft 18, to which are fixedly attached the two wheels 17 17, passes through the lower portion of the receptacle, that portion of the shaft 19 within the receptacle being of rectangular formation.

Fixedly attached to the rectangular shaft 19 are angle arms 20, 20.

Two shafts 21, 22 pass through the receptacle, the inner portions 23, 24 of said shafts being rectangular, the shaft 23 carrying the mixing blades 25, 25, and the shaft 241- carrying the mixing blades 26, 26.

Exterior of the side 10, the shaft 22 carries the fiipedly attached sprocket 27, the shaft 21 carries the fixedly attached sprocket 28 and the shaft 18 carries the fixedly attached sprocket 29. The side 10 also carries the sprocket idler 30.

A link chain 31 passes over the sprockets 27, 28, 29 and 30, so that a forward movement of the receptacle will cause the series of mixing blades 25, 25 and 26, 26 to move inwardly with respect to each other and downwardly with respect to the receptacle.

Carried'by each side of the back 13 is an angular support, one arm of which 32 is fixedly attached to the lower portion of the back 13 and the other arm 33 is attached to the bottom let. This support has the rear- -wardl extended member 34 having a vertical s ot 35 therein.

, A revoluble shaft 36 extends through and is revolublewithin the two supporting arms 32 32. p

lfiixedly attached to the shaft 36 is a rais ing arm 37, the lower portion of which 38 1s inclined rearwardly -and downwardly and has a longitudinal slot 39. The upper portion ofthe arm 37 carries a spring catch 40, thetooth of which is capable of placement in a series of recesses 41, 42, 43 and 44 in the segmental arm 45 which is attached to the back 13. Fixedly attached to the shaft 36 is a counterweight 46.

Carried by the members 34, 34, and passing through the slots 35, 35, is a leveling or scraping device 47, one end of which 48 1s cylindrical and passes through the opening 39 of the arm member 38.

A cross-bar 49,- havin theannularmember 50 is fixedly attache to the forward portion of the receptacle by the supports 51, 51,

52, 52. Pivotally attached to the annular member 50 is an annular member 53 carryingthe shaft 54 upon which the two traction wheels 55, 55 are revoluble. The annular member 53 also carries the. eye-bar 56 pivot'- ally attached at 57.

he operation of my device is as follows The eye-bar 56 is attached to the rear of a truck receptacle carrying a large quantityof soft asphalt and is so inclined that the contents therein flow gradually into the device. The truck is then moved forwardly dragging the device after it. .The movement ofthe traction wheels 17 17, revolves the mixing blades 25, 25, 26, 26, thus mixing the asphalt falling thereon-and passing it downwardly upon the revolving members 20, 20, which in turn cause the 4 asphalt to pass outward] through the longitudinal o ning 15.

It will be noted that as t e members 20, 20, revolve they formpockets with the bottom 14, the contents of which pass through the opening 15, and hence, the amount of asphalt delivered will depend upon the capacity of these pockets.

As it is generally desirable that a certain amount of asphalt be delivered in orderto produce a layer of desired thickness, it is advisable that the capacity of these pockets be changeable in order to meet different requirements.

This is accomplished by the attachment of channel irons to the members 20, 20, as infoll dicated in Figure 7 as.follows:"-

Channel irons 58, 58 of the desired are introduced through the opening 15 and bolted to the members 20, 20. The shape of the channel irons will therefore control the size of the pockets.

The operation of the leveling device is as ows:-

c The recesses 41, 42 and 43am so positioned lower rear side of said shape the road, such as a man-hole, and it is necessary to raise the sore er 47, the arm 37 is raised, thus raising tie scraper verticall along the slot 35, and it may be locked in this raised position, if desired, by inserting the catch 40 in notch 44.

, It will thus be seen that our device presents a means whereby a continuous layer of asphalt of ractically an desired thickness may be laid upon a roa bed, the amount of asphalt deposited bein determined by the size of the as halt poc lcets and the asphalt thus deposited being leveled into the desired thickness of layer.
